We only know which neurons are connected, not the weights.
More than that, real neurons don’t behave anything like the ones we model in neural networks - real ones signal with pulses, in a manner where the timing seems as significant as the magnitude of the impulse. Typically simulated neural networks use continuous analog values instead of pulses and a sigmoid function to shape the output. Basically, the “wiring” might be the same but nothing beyond that is. - - - Actually,…
Isnt there also a theory and some evidence that the connectome is not enough to model a brain. Based on the fact that butterlies connectome dissolves during metamorphosis to butterfly but it still remembers things from before that stage of life.

MMAcevedo (Mnemonic Map/Acevedo), also known as Miguel, is the earliest executable image of a human brain. It is a snapshot of the living brain of neurology graduate Miguel Acevedo Álvarez (2010–2073), taken by researchers at the Uplift Laboratory at the University of New Mexico on August 1, 2031

That says the butterflies have a back up mechanism, it doesn't say that connectomes are insufficient for modelling running neural processes.
We don't actually know what is sufficient for modelling neural processes until we do it. But we can't really do that until we figure out how to read all the connection strengths.

No, the nervous system is one of those things that don't fully dissolve. Partial info retention is perfectly consistent with partial connectome retention.

If your circle of empathy includes fruit flies, fuck no, we murdered so many of those guys to figure out how their tiny brains work. If you do not think of fruit flies as moral patients, sure, yeah, who cares, they're like just fruit flies you know?
If your circle of empathy doesn’t include fruit flies, endeavor to expand your circular of empathy until it does. Goto 0.
If your circle of empathy includes fruit flies, shrink and prune until it no longer does.

Ever met a Jain?
AFAIK, Jains consume diary products.
You tell me where the consumption of dairy products must result in harm to the cow. I grew up around small-scale, subsistence-level dairy farming, it doesn’t inherently require any more suffering than either egg-harvesting or apple-growing inherently do.
A Jain doesn’t have to purchase milk from a factory farmer.
And AFAIK even the most stringent vegans don’t brush insects from their path with every step, or avoid onions and carrots because it causes death.
